FIND out how fast you are with our Amstrad reaction timer. Are you quicker off the mark than your friends? Does your reaction time vary as the day goes on? Kids, are you faster than your parents? Type in this listing and find out.

When you run the program a white bar will appear on the left of the screen. Watch it carefully because soon it's going to change colour, beeping every time to give you a warning.

At first it becomes red. Then, like a set of traffic lights, it will change to yellow. This tells you to be prepared because green is the next colour and you're going to have to react quickly.

As soon as it turns to green (but not before!) you have to press the space bar. The Amstrad will then tell you how fast your reactions are and what it thinks of them.
